BURGLAR-ALARM.

SPECIFICATION forming part of Letters Patent 0. 430,979, dated June 24, 1890.

Application filed September 21, 3 Serial No. 324, 14 N m l-l To all whom it may concern:

Be it known that I, JAMES WINEG RDE'N, a citizen of the United States, residing at the city of Grand Rapids, in the county of Kent and State of Michigan, have invented a certain newand useful Burglar-Alarm, of which the following is a specification.

Myinvention relates toa system of burglaralarms, to be applied to buildings, consisting of electric circuit-closers automatically operated by pressure caused by the opening of windows or doors and also by pressure upon the window or window-sash, and may be applied in connection with stationary lines of telegraph or telephone for the purpose of giving the alarm at points outside of the building to which the system of burglar-alarm is applied, the object of the invention being to cause an alarm to be given at any required point by means of the construction and arrangement of parts more fully. described herein. These objects are accomplished by means of the mechanism illustrated in the accompanying drawings, in which Figure 1 shows-a front elevation of a window-sash and a part of the window-jamb, showing the circuit-closer upon the inner surface of the sash, also a circuit-closer between the janib and the sash, and a circuittransferrer. Fig. 2 is a perspective View of one edge of a window-sash, designed to show the connection of the automatic circuit-closer and metallic conducting-strips. Fig. 3 is an elevation of that portion of a window jamb which comes in contact with the window-sash, showing a front view of a circuit-closer, also the electric transfer strips. elevation of my automatic circuit-closer which is applied to the inside of the sash, being the same device shown on the left-hand portion of Fig. 1. Fig. 5 is an elevation of a sash and sash-stop with an automatic circuitcloser placed so as to be held open by means of the sash; and Fig. 6 is an elevation of awindowstop, showing the position of the automatic circuit-closer when the pressure from the sash has been removed.

The sash is constructed in the ordinary manner. Near the edge of the sash is placed the automatic circuit-closer shown in Fig. 1, which consists of the part 10, which is made of Fig. at is a sidefibrouspaperorsomenon-conductingmaterial. Attached to one end of the base or part 10 is a metallic 1 plate 11. Attached to the other end is a metallic spring 12. This circuitcloser, constructed as above described, is attached to the window-sash between the sash and the sash-stop by means of a pin 13, or in any other suitable manner. On the edge of the sash which comes in contact with the jamb I provide two metallic strips or conductors. (Shown in Fig. 2 by 5 and 6.) The metallic plate 11 is connected by a wire or other conductor to the metallic plate 6. The metallic spring 12 is connected by wire 9 to the plate 5.

Upon the jamb I place two plates 8 8, which are preferably made of I brass, and which are bent so as to come in contact continuously with the plates 5 and 6, one of which electric connecting-plates is shown in Fig. 1. These plates serve the purpose merely of transferring the electricity from the strips5 and 6 to the wires 21 and 22, and from thence to the battery.

The operation of this part of my invention is as follows: The automatic circuit-closer (shown in detail in Fig. 4) is placed upon the inside of the sash and between the sash and the strip, usually known as a window-stop, in such a manner that the spring 12 is raised a slight distance from the metal plate 20, thus holding the electric circuit open. Any press ore from the outside of the window, either upon the glass or upon the sash, will cause the spring 12 to come in contact with the plate 11, thereby connecting or closing the circuit. The electricity goes to the wire 20, and from thence to one of the transfers 8, through the battery, back through the plate 5, an d wires 9, making a complete circuit, upon which circuit is placed a bell, which bell is located at any point in the building required. This circuit-closer is peculiarly adapted to the win dow-sash to be operated by pressure from the outside.

In Fig. 5 I have shown an edge view of the sash and of a portion of the stop. 13 represents an automatic circuitcloser, consisting of a spring placed upon the stop, one end of which is curved or bent so as to pass through the opening in the stop. The spring 13 is a conductor, and also the plate 12, both of which are connected by wires and other suitable connections to the battery. The point of contact which closes the circuit is shown in Fig. 6 by 14. When the window-sash is in position, the pressure of the sash holds the spring 13 out of connection, as shown in Fig. 5; but on removing the sash the spring automatically connects at point 14 with the plate or conductor 12, and the electric current is completed and the bell caused to be rung. This device or circuit closer is not only adapted for use in connection with windows, but also with doors. YVith windows the connection is made upon the removal of the window-sash. lVhen applied to doors, the connection is made or circuit closed when the door is open.

In Fig. 3, 7 represents a forked circuit-closer. This is placed upon the window-jainb so that the upper point is somewhat above the plates 5 and 6 on the window-sash, and are so placed that when the window-sash is raised a short distance the plates 5 and 6 are brought in contact with the arms of 7 '7, thereby connecting the circuit through the plates 5 6, electric transfers 8 S, and wires 21.22 to the battery. This portion of my invention is adapted to windows or other openings which slide in grooves or otherwise.

In order to operate my invention in connection with a telephone, all that is necessary to do is to connect the wires with a telephonewire, thus ringing the bell at the central ofiice of the telephone company. It is evident that this construction may be applied not only to single buildings, but to numerous buildings situated at a considerable distance from each other, if found desirable.

I wish it to be understood that I do not here- I in claim the combinatiomwith the battery and the electric-bell alarm, of two plates secured parallel to each other on the edge of the window-sash, a circuit-closer secured to the-window-frame and two electric transfers secured to the windw-fraine below said circuit-closer, respectively connected with the battery in the bell-circuit, and continuously in contact with the parallel plates on the sash, as such is not my invention.

Having thus described my invention, what Iclaim to have invented, and desire to secure by Letters Patent, is-

1. In a burglar-alarm, the combination of a circuitcloser, the window-sash and windowstop, and suitable connections with the battery and alarm-bell, said circuit-closer placed between the sash and stop, and adapted to close the circuit automaticallyin case of lateral pressure exerted from without the building upon the window-sash or window-glass to move the sash toward the window-stop, substantially as described.

2. The combination, witha window-sash and a window-stop, of a contact-plate 11' and a circuitclosing spring 12, bot-h attached to the window-sash between the latter and the window-stop, the two vertical-metal plates 5 and 6, secured to the edge of the sash next to the jamb, and respectively connected with the contact-plate and the spring, the two plates 8 fixed on the jamb andcontinuously in metallic contact with the vertical plates on the edge of the sash, and a source of electricity and connections between the latter and the plates on the jamb, substantially as described.

In witness whereof I have hereunto set my hand and seal in the presence of two witnesses.
